During spring service
a Volvo Penta mechanic
filled our SailDrive
with Diesel engine oil
(15W40 grade) instead of ATF oil
. He claimed, that he received a service
bulletin from Volvo
permitting this. However, was reluctant to produce anything on paper. To me it seemed strange, as the composition and viscosity of both fluids is quite different.
My question is, does anyone know about such recommendation from Volvo Penta
is a year old and I think it is the ZF 10 unit made for Volvo by ZF.
